Thank you for getting back with the requested necessary information.
From your symptom analysis and correlating it with the medical history that I have gathered from you I feel that the possibilities are -
Premature ventricular contractions. These are also very common and do not require any treatment unless you have the symptoms which I have inquired above.
Mitral valve prolapse which is extremely common in general population and its not be worried about.
Bicuspid aortic valve - but again this needs echocardiography.
Stress or anxiety associated symptoms.
I have put this as the last possibility, because I would like to consider this only after rolling out the organic causes.
But something I am glad to assure you is that you do not have anything serious cardiac was going on.
May I suggest you discuss these possibilities with your primary care physician and get yourself appropriately evaluated and managed please.
